Paper cutter is the standard supporting machinery and equipment of the printing press, mainly used to deal with the pre and post printing paper cutting needs. Paper cutter from the beginning of the mechanical paper cutter to the development of tape control room paper cutter, and the development of microcomputer program control, color display, full image operation to guide the visual processing and computer-aided cutting external programming and editing of production data cutting system, so that the paper cutter production preparation time is shorter, higher cutting accuracy, lower labor intensity, and better operational security.

Now the paper cutter is roughly divided into three categories, divided into manual paper cutter, electric paper cutter and hydraulic paper cutter; manual paper cutter is the traditional paper cutter, also known as the cutting knife, cut the paper max-width='100%' width is small, generally used for simple text cutting processing; and electric paper cutter is a purely mechanical structure to control the operation of the cutter, cut the paper conveniently, suitable for batch processing of documents; hydraulic paper cutter is the internal structure contains hydraulic fluid, through the hydraulic oil Hydraulic paper cutter is the internal structure contains hydraulic oil, through the operation of hydraulic oil, to control the operation of the cutter, because the electric paper cutter in cutting some soft paper, there may be cutting impervious, not suitable for some of the many materials to deal with the paper industry. Hydraulic paper cutter can cut rice paper, leather, paper and other materials of the text, processing speed, so in the library, printing and publishing in a wide range of applications.
